Stabilizing conditions of metal mercury in mercury
The cost-effective conversion of Hg to HgS is the key to mercury sulfurized stabilization. Fortunately, it has been proved that ball milling of liquid mercury and sulfur can be completely converted into HgS in a short time at room temperature [20,22,23]. Such ball milling process is the famous MC method.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

What is a Ball Mill? | Economy Ball Mill
What is a Ball Mill? A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.

ods, a safer alternative is to use the ball-mill method and heat treatment to react mercury with sulfide. In this method, the mixture of mercury and sulfur powder was ground through a ball mill first, producingβ-HgS [23]. In the subsequent step, the -HgS was β heated without O 2 to induce a crystal phase switch and transform it into α-HgS.

Metallic Mercury is a dense liquid that vaporizes easily at room temperature. Metallic mercury is not easily absorbed into unbroken skin. However, it vaporizes, even at room temperature. The higher the temperature, the more vapors are released. Mercury vapors are colorless and odorless, though they can be seen with the aid of an ultraviolet light.

Ball Milling
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
